How to grow a cactus? These care methods are worth trying
Alocasia (also known as "Dripping Guanyin") is a green leafy plant. When it has plenty of water, let's take a look together at how to care for Alocasia.
How to grow Alocasia
1. Suitable growing temperature for Alocasia: 20-25°C is the most suitable growing temperature for Alocasia. When the room temperature is below 18°C, Alocasia will enter a dormant period and stop growing. Alocasia likes a warm, humid, semi-shaded environment. During cultivation, you must pay special attention to the changes of the seasons. Especially now that summer is about to begin, be particularly careful to place Alocasia in a semi-shaded, well-ventilated spot, and you need to spray water on the leaves of Alocasia several times to maintain air humidity. Avoid excessively high temperatures causing abnormalities in Alocasia. Alocasia is not very cold-resistant; depending on the temperature differences between north and south, it needs to be moved indoors in autumn and winter.
2. How to fertilize Alocasia: The fertilizing cycle for Alocasia is once a month. Every 2 weeks you must give Alocasia an additional feeding. And you need to moisten the potting soil of Alocasia. Fertilizing requirements: use nitrogen fertilizer mixed with thin liquid fertilizer such as phosphorus and potassium fertilizers as a supplement. When topdressing, avoid pouring the fertilizing water onto the leaf sheaths, as this will cause Alocasia to rot. If you want the leaves of Alocasia to be large and green, you can apply some ferrous sulfate to achieve this. If you want Alocasia to look beautiful and attractive, avoid a lack of fertilizer; once a fertilizer deficiency occurs, the stem of Alocasia will shrivel and become bare. The Alocasia you usually see comes in large and small sizes. If you want to keep Alocasia small and attractive, when the seedling grows to the height you want, such as 40cm, spray the whole plant with a 2% paclobutrazol solution, and in the later growth of Alocasia you will find that the growth height of Alocasia will not exceed 40cm. If Alocasia continues to grow, you can spray the whole plant again. Generally, spraying once about every half a year can achieve the effect of controlling height.
3. Notes on watering: In summer, you can water Alocasia more. People often say that the stems of the Alocasia they grow rot. This is caused by water accumulation. If you give Alocasia too much water, this situation will occur, so when watering you must grasp the right amount. In winter, Alocasia will enter a long dormant period, so in winter you should control watering and stop fertilizing.
4. The lighting issue for Alocasia: For plants that like semi-shade, direct sunlight is the biggest taboo. When the leaves of the Alocasia you are growing droop, it may be due to a lack of fertilizer. At this time you need to add some liquid fertilizer to Alocasia. When Alocasia enters its flowering period, ensure 3-5 hours of light every day. Otherwise, the flower buds will turn green and the leaf stalks will elongate, affecting its appearance.
What causes the leaves of Alocasia to turn yellow?
Answer: The potting soil of Alocasia has been too wet or too dry for a long time, and watering has not been done as soon as the soil dries. Watering "halfway", that is, watering is not thorough, and no water seepage appears at the bottom of the Alocasia pot. In winter, if it gets cold, the root system of Alocasia has already been frostbitten. If the leaves of Alocasia are not sprayed and cleaned for a long time, dust accumulates and hinders photosynthesis. After winter, Alocasia is in a hurry to be moved outdoors and placed in a warm place to bask in the sun, and it temporarily cannot adapt to the sudden climate change. Alocasia has been placed in a poorly ventilated environment for a long time.
What should you do if you are poisoned by touching the sap of Alocasia?
Answer: It is recommended to use vinegar to neutralize the poison. Rinse with plenty of clean water. The toxic components are calcium oxalate and sapotoxin; after the skin comes into contact with the sap, it itches; contact with the eyes causes blindness. Folk remedy: boil a little vinegar with ginger juice, and take it orally or gargle with it to neutralize the poison. If the poisoning symptoms are obvious, it is recommended to go to the hospital for medical treatment.
What should you do if Alocasia has root rot?
Answer: Alocasia is prone to root rot in summer, mainly caused by potting soil that is too wet. Pull up the Alocasia, cut off the rotten roots; when cutting the roots, wear rubber gloves (Alocasia is poisonous! Those with skin allergies should be careful.), and cut off a little of the healthy tissue near the rotten part. Dry it, and replant it after the wound heals. Plant it in plain sand or sandy loam, and do not water it for the time being; wait until the potting soil is completely dry before watering. Do the same from then on: do not water unless it is dry. In addition, place it in a ventilated place.
How should you care for Alocasia?
Answer: In winter its transpiration will decrease. If it is a newly transplanted seedling, after the soil it came with is moistened, it is enough to keep the environment around the seedling moist; use a spray bottle to mist the surrounding environment. If it is an old plant, feel the surface soil with your hand, and only water when it is dry, but do not water too much, because when the temperature is below 18°C, Alocasia goes dormant and hardly grows, so it does not need much water; otherwise the roots will rot.
